Description

Assembled building vibration damper with multi-direction energy consumption characteristic
Technical Field
The invention relates to the field of building structure vibration control, in particular to an assembly type building vibration damping device with multidirectional energy consumption characteristics.
Background
China is not only a country with frequent earthquakes, but also a country with serious wind disaster threat. The damage of building structure caused by earthquake and strong wind causes huge casualties and economic property loss for China. Therefore, how to minimize the influence of earthquakes and strong winds on the building structure has become a practical engineering problem that civil engineering technicians must solve.
For reducing the loss caused by earthquake and strong wind, the most effective way is to arrange an energy consumption vibration damper on the building structure, and absorb the input energy of earthquake or strong wind through the hysteresis energy consumption of the energy consumption vibration damper, thereby effectively reducing the dynamic response of the building structure. At present, the commonly used dissipative vibration damping devices include metal dissipative devices, viscoelastic dissipative devices, viscous dissipative devices, etc., but these commonly used dissipative vibration damping devices can only consume input energy in a single direction. In fact, the earthquake and wind load borne by the building structure are multidirectional, so that the energy dissipation and vibration reduction devices need to be arranged in different directions of the building structure to provide additional damping in different directions for the building structure, and meanwhile, the construction cost of the building structure is also increased.
The foamed aluminum/high molecular polymer composite material is one kind of high damping material obtained through filling high molecular polymer into three-dimensionally connected open-cell foamed aluminum. The high damping material can really combine the respective energy consumption performance of aluminum and high molecular polymer, such as the friction characteristic of aluminum and the viscoelasticity deformation capability of the high molecular polymer. Therefore, if the energy consumption characteristics of the high damping material can be reasonably utilized and developed into a novel energy consumption damping device, a new means is necessarily provided for damping control of the building structure.
Disclosure of Invention

Furthermore, the high damping material layer is made of a composite material obtained by filling a high molecular polymer into pores of open-cell foamed aluminum; the rigidity of the high damping material layer is smaller than that of the spring.
Furthermore, the section of the steel member is in the form of a round steel pipe, a square steel pipe or I-shaped steel.

The energy consumption principle of the assembly type building vibration damper is as follows: when earthquake and strong wind act in horizontal direction, the building structure can dissipate energy through the interface friction between the high damping material layer in the device and the middle metal plate in horizontal direction; when the vertical earthquake acts, the building structure can dissipate energy through the high-damping material layer and the middle metal plate in the device in the vertical cyclic compression mode, and then the device can protect the building structure from multiple directions.
